POWER SUPPLY WITH CURRENT SHARING CONTROL AND THE BATTERY MODULE

摘要

A power supply with current sharing control and its battery module are disclosed. Wherein, the power supply comprises a main controller and a plurality of battery modules in a parallel connection. The battery modules output a plurality of current status signals according to current quantities of output currents output by their respective battery units. The main controller outputs a plurality of current sharing control instructions according to the current status signals, thereby commanding the battery modules to adjust the output current quantities of the output currents. Therefore, the battery modules respectively adjust the output currents of the battery units by themselves to prevent the battery units from being damaged due to a forced discharge and to equalize the current quantities of the output currents.
